The use of the arthroscope as an adjunct in the resection of a chondroblastoma of the femoral head.

We present a case of the use of an arthroscope as an adjunct in the resection of a tumor (chondroblastoma) of the femoral head. Use of the endoscope in this case allowed preservation of the femoral head and neck. Although the arthroscope has been used intraarticularly for the resection of tumors, to our knowledge it has not been used endosteally.
